Abstract

Un sistema de desecante líquido (100) para controlar una temperatura dentro de un recinto. El sistema (100) incluye un sistema enfriador evaporativo de desecante líquido (LDEC) (110) configurado para enfriar una corriente de aire entrante (AA) que ingresa en el recinto mediante el uso de un primer desecante líquido (312); un sistema de bomba de humedad de desecante líquido (LDHR) (120) configurado para remover la humedad de una corriente de aire húmedo (AD) que sale del recinto mediante el uso de un segundo desecante líquido (412); y un sistema de almacenamiento (130) conectado fluidamente al sistema LDEC (110) y al sistema LDHR (120) y configurado para almacenar separadamente el primer desecante líquido (312) y el segundo desecante líquido (412). La corriente de aire húmedo (AD) incluye vapores de agua del primer desecante líquido (312) y del interior de recinto.A liquid desiccant system (100) to control a temperature within an enclosure. The system (100) includes a liquid desiccant evaporative cooler (LDEC) system (110) configured to cool an incoming air stream (AA) entering the enclosure through the use of a first liquid desiccant (312); a Liquid Desiccant Moisture Pump (LDHR) system (120) configured to remove moisture from a stream of moist air (AD) exiting the enclosure through the use of a second liquid desiccant (412); and a storage system (130) fluidly connected to the LDEC system (110) and the LDHR system (120) and configured to separately store the first liquid desiccant (312) and the second liquid desiccant (412). The humid air stream (AD) includes water vapors from the first liquid desiccant (312) and from the interior of the enclosure.
